Comparing Hole Extraction Efficiencies in Perovskite Solar Cells using PLQY
Efficient extraction of charge carriers is vital for the creation of high-efficiency solar cells. Photoluminescence is proportional to the number of charge carriers in the perovskite and sensitive to charge transfer into adjacent layers. This makes PL based techniques invaluable for investigating the performance of new extraction layers. In this app note, the extraction efficiency of a VACNT hole extraction layer is investigated using PL spectroscopy with a Photoluminescence Spectrometer.
